Tis is a good 'snapshot', as opposed to a 'photograph'. I sppose there is a difference. Perhaps the condition could be that the subject of a snapshot should not know that they are being photographed. I think this is the case here, and all the better for it.
Interesting shot... perhaps a little too like a snapshot. Slight overexposure resulting in burnt out highlights. The boy doesn't seem to be very sharp, and there is bad artifacting everywhere, possibly as a result of applying sharpening in PS to a photo that wasn't too sharp to start with. This particularly affects the texture of sand. Perhaps a little too much red overall. I think the main problem with this shot for me is that the viewer's eye is pulled in different directions. The two subjects are both looking out of the frame in different directions so there is no clear point of focus.
